摘要： An internal antenna system (200) for reducing interference in a wireless communication device (100) is provided. The internal antenna system (200) comprises an antenna (202) and a housing (110). The housing is configured to reduce interference in the transmission caused by the metal surface of the housing. The housing is made of or plated with an electromagnetically transparent decorative metal (ETDM). The housing has metal islands, which are separated from each other by gaps. These gaps in the ETDM surface allow the radio frequency (RF) energy of signals transmitted by the antenna to pass through.

摘要： Improved fluxless soldering processes are disclosed. In accordance with one technique, a solder preform having a plurality of voids formed on its primary surfaces is disposed between metallized surfaces of a pair of members to be joined. Upon reaching the reflow temperature, fresh solder flows into the voids and wets portions of the metallized surfaces, thus overcoming the solder surface oxidation problem common to fluxless soldering processes. In accordance with another technique, a solder preform having primary surfaces coated with a thin layer of a noble metal is employed. The noble metal substantially prevents oxidation of the solder performs surfaces while the preform is heated to reach reflow temperature. As the solder temperature increases, portions of the noble metal are dissolved into the bulk solder material. Thus, during reflow, non-oxidized bulk solder material is enabled to wet the metallized surfaces of the pair of members.
